Title: Method for transmitting a digital broadband signal in a tributary unit concatenation via a network of a synchronous digital multiplex hierarchy
Inventor: MUELLER HORST
IPC: H04J3/06
Filed: 1990-11-27
Granted: 1999-11-09
Abstract: Method for transmitting a digital broadband signal in a tributary unit concatenation via a network of a synchronous digital multiplex hierarchy. A pointer for positional identification in a frame is allocated to the first tributary unit in a tributary unit concatenation; instead of a pointer, the further tributary units receive a concatenation indicator. Every cross-connect equipment along a transmission link recognizes the tributary unit concatenation and forwards the tributary units thereof in the correct sequence. When a clock matching is required in the case of a first tributary unit, a pointer skip is initiated at all further tributary units. This requires hardware and software.      This is eliminated when all tributary units (TU-12 1 through TU-12 5) containing the broadband signal (DSa) have a pointer (PTR1 through PTR5) having the value of the positional identification of the first tributary unit (TU-12 1) allocated to them. The individual tributary units (TU-12 1 through TU-12 5) can then pass the cross-connect equipment, if necessary with an individual pointer skip (PS), independently of one another. A restoration of the tributary unit concatenation occurs at the reception side after the recognition of the pointers (PTR1 through PTR5) in that leading tributary units (TU-12 2, TU-12 5) are delayed by delay elements (L2, L5).

Abstract: In a speech parameter encoding method of encoding an input speech signal into a sequence of encoded signals, vector quantization is carried out through a plurality of vector quantizers which are connected in cascade to one another through subtractors and which cooperate with code books, respectively. Such a cascade connection of the vector quantizers may be supplied with the input speech signal either at every frame or at every subframe shorter than the frame to produce a set of code vector candidates from each of the vector quantizers.          Each set of the code vector candidates is sent to a cumulative distortion calculator to select an optimum combination of the code vector candidates and to produce, as the encoded signals, an index representative of the optimum combination.  Alternatively, a sequence of coefficients which represent a spectrum parameter is calculated at every frame and is divided into a plurality of coefficient groups each of which is subjected to vector quantization to produce a plurality of code vector candidates for each coefficient group.  Cumulative distortions are calculated for combinations of the code vector candidates to select an optimum combination.

Abstract: A self-locking divider plate made of flat sheet metal is provided in an electrical box to form separate compartments. The electrical box has several upper and lower front ledges which form aligned slots which in turn, cooperate to receive the divider plate. The side edges of the divider plate has a biased sheared tab which locks the plate in place between the slots upon installation of the plate into the box. These sheared tabs extend outwardly from one of the planar surfaces of the plate.  When the plate is inserted into two aligned front slots, the tabs are pushed inwardly toward the planar surface of the plate, and spring back to their normal position when the plate is in its proper position in the box. The tabs engage an inside surface of the ledges when the plate is moved outwardly from the box to prevent its accidental removal. Tangs on the back edge of the plate fit into slots in the back wall of the box, and tangs on a front edge of the plate adjacent to the sheared tabs engage the walls of the slots to position and secure the divider plate within the box.
